Lyone, a peaceful city is turned inside out when a horde of strange monsters appear out of thin air. Amidst the chaos, Vincent Crow, a Chevalier for a secret organization to control the situation reluctantly accepts the help from one of the few surviving police officers, a young woman named Gabrielle Dutton.
Upon reaching 37th precinct, Vincent and Gabrielle become aware that by dawn, the organization in order to stop the creatures from invading neighboring cities, they have to destroy Lyone. But can’t leave the city until he completes his mission, and Gabrielle again offers her help; but as they leave the precinct, a large creature breaks into the precinct and assaults against Vincent and Gabrielle.
Narrowly they manage to shake-off the creature, but Vincent is heavily injured during their escape. But despite the injury, Vincent still wants to continue his mission, and Gabrielle asks him why.
Vincent had a normal life, until his father came across a strange ivory cube that turned out to be a summoning device; his family is killed but Vincent is saved by Chevaliers from the organization, he decides to join them to prevent what happened to his family to happen anyone else. During his training years he meets Noah, another young-man with a similar story to his own.
Shortly after their first mission, their mentor, Landis, disappears and considered to have defected to the Sect; a cult that worships the creatures the organization is trying to destroy. Noah is captured during a mission, and betrays Vincent and the organization and sets off with a handful of artifacts from the organization’s vault.
The organization believes that it was Noah that summoned the creatures that took over Lyone, and to clear his name, Vincent accepts joins the mission.
But the real culprit is a man named Raphael Vaz, a microbiologist that was captured along with his family by the Sect. During the time he spent in captivity, Vaz discovered a new power that eventually allowed him to escape, and with Noah’s help, carried a successful attack on the organization’s HQ and steal several artifacts he needed to complete his research.
In Lyone he found everything he needed to continue his experiments and summoning the creatures that lay the city to waste was part of his plan; but he didn’t count on that the “Black Wraith,” would be summoned as well. The Wraith killed Vaz, but his soul was carried into another body by a shadow creature he had been working on since his imprisonment. He was relieved when the Wraith attacked Vincent in the 37th precinct, but Vaz was challenged several hours ago by the police commissioner, and after getting killed second time, he broke into the makeshift command center set up by Dario Bevan, the police commissioner and Gabrielle’s uncle.
Vincent and Gabrielle fight the Wraith one last time in the subway lines of the city, later they split up: Vincent will head to the old-museum where the relic he was sent to recover can be found, while Gabrielle heads back and recover Vincent’s airship so they can escape the city.
Vincent’s confronts Vaz and his shadow creature, but until he gets rid of the shadow creature, he would never land a hit on Vaz. He reveals a tattoo imprinted into his left arm, a “Nephilim seal,” a powerful curse that sent the shadow creature running and finally kills its master.
While Vincent heads to recover the artifact, Gabrielle has to deal with one last creature. After the brutal fight, he recognizes the creature; Vaz had transformed her uncle into the hideous beast she just killed and vows to get even.
As Vincent races to the rooftop of the old museum, a large, worm-like creature breaks into the old-museum and chases Vincent through the rooftop as the first rays of dawn bathe the hell-bound city.
Gabrielle rescues Vincent just as the bombs were dropping; together they fly into the horizon. But Vincent knows that the nightmare isn’t over yet. Continue reading
